Trans, trans-1,2,4-cyclohexanetricarboxylic acid-1,2-anhydride represented by the following formula 1:
a cyclohexanetricarboxylic anhydride being liquid at ordinary temperatures which contains such a anhydride, and a production method thereof. The cyclohexanetricarboxylic anhydride being liquid at ordinary temperatures is produced by melting 1,2,4-cyclohexanetricarboxylic acid and/or 1,2,4-cyclohexanetricarboxylic acid-1,2-anhydride at 180 to 300° C. under heating. Since the cyclohexanetricarboxylic anhydride is liquid at ordinary temperatures. it is advantageously used in industrial applications such as raw materials or modifiers for coating compositions, adhesives, shaped articles, sealing resins for photosemiconductors, curing agents and polyimide resins, raw materials for plasticizers and lubricant oils, intermediates for medicines and agricultural chemicals, raw material for coating resins, raw material for toner resins, etc.
以下是Trans,trans-1,2,4-环己烷三羧酸酐的化学式1:一种在常温下为液态的环己烷三羧酸酐,其含有此类酐,以及其生产方法。在加热下,将1,2,4-环己烷三羧酸和/或1,2,4-环己烷三羧酸酐在180至300℃熔化,从而生产出在常温下为液态的环己烷三羧酸酐。由于环己烷三羧酸酐在常温下为液态,因此它可以优势地用于工业应用,例如涂料组分、粘合剂、成型品、光电导密封树脂、固化剂和聚酰亚胺树脂的原材料或改性剂、增塑剂和润滑油的原材料、药品和农药的中间体、涂料树脂的原材料、色调树脂的原材料等。
